Cryotherapy, also known as cryosurgery or cryoablation, involves using extreme cold to destroy unwanted tissues. This method is known for its efficacy and minimal invasiveness. By applying cryogens such as liquid nitrogen, cryotherapy creates localized freezing zones, leading to cellular injury and subsequent tissue necrosis.

Cryotherapy works by inducing controlled tissue destruction. The extreme cold causes ice crystals to form inside the cells, leading to cell rupture and death. The treated area then undergoes inflammation and scabbing, with the dead tissue gradually sloughing off, allowing healthy skin to regenerate.

Cryotherapy is a versatile tool in dermatology, useful for treating a variety of cutaneous lesions. At Hazel Clinic, Dr. Susana Fontana uses cryotherapy for:

Skin Tags: Quick and effective removal.

Warts: Standard treatment for warts caused by the human papillomavirus.

Precancerous Lesions: Such as actinic keratosis, which can develop into skin cancer if untreated.

Other Skin Growths: Including seborrheic keratoses, sunspots, and molluscum contagiosum.

Hypertrophic/Keloid Scars: Reducing size and appearance.

The cryotherapy procedure at Hazel Clinic is meticulously planned and executed to ensure the best outcomes:

External Cryotherapy: Involves applying a cryogen using spray devices or cotton swabs directly onto the skin.

Dr. Fontana tailors each procedure to the patient’s specific condition, optimizing efficacy and minimizing discomfort.

Proper aftercare is crucial for optimal healing and minimizing complications:

Immediate Effects: Mild stinging during the procedure, followed by redness and swelling within a few hours.

Healing Process: The treated area will form a blister, scab, or crust that typically falls off within two weeks, revealing new, healthy skin underneath.

Aftercare Tips: Apply ointment like Vaseline twice daily, keep the area clean, and avoid popping blisters to prevent infection. Covering the treated area with a Band-Aid can protect it, and applying gauze or tissue with firm pressure can help if bleeding occurs.

While cryotherapy offers numerous benefits, it also carries some risks:

Benefits: Quick procedure, minimal scarring, high patient satisfaction, effective for various skin conditions.

Risks: Pain, bleeding, infection, nerve damage, pigmentary changes, and in rare cases, recurrence of the treated lesion. Adherence to aftercare protocols and close monitoring can mitigate these risks.

Cryotherapy is continually evolving, with ongoing research and technological advancements:

Refinement of Techniques: Enhancing cryogenic delivery systems and optimizing treatment parameters.

New Indications: Exploring novel uses of cryotherapy in other medical fields beyond dermatology.

Does Cryotherapy Hurt?

Cryotherapy typically causes mild stinging during treatment, lasting about five minutes. Most patients find the discomfort tolerable and the procedure quick.

What Happens After Treatment?

The treated area will swell and redden within a few hours. A blister or scab will form and fall off within two weeks, revealing healthy skin.

Does Cryotherapy Leave a Scar?

Generally, cryotherapy does not leave a scar but may cause temporary discoloration, especially in deeper treatments or on darker skin tones. This discoloration usually fades over time.

How to Prepare for Cryotherapy?

No special preparation is needed. Removing makeup, creams, or jewelry from the treatment area is advisable. The doctor will sterilize the skin before the procedure.

Allow the natural blistering and scabbing process. Apply ointments like Vaseline, avoid applying other products, and refrain from popping blisters to prevent infection and ensure proper healing.
